CHAIN-PUMP.

SPECIFICATION forming part of Letters Patent No. 449,598, dated March 31, 1891.

Application filed September 15, 1890. Serial No. 365,046- (No model.)

To all whom it may concern:

Be it known that I, BEVERLY B. SPENOE, a citizen of the United States, residing at Midland, in the county of Rutherford and State of Tennessee, have invented a new and useful Chain-Pump, of which the following is a specification.

My invention relates to improvements in piping for chain-pumps adapted to be used in wells of small diameter, such as bored wells. In chain-pumps ordinarily in use the chain after passing over the wheel at the top drops loosely down in the well and takes up considerable space, rendering it unfit to be used in wells of small diameter. My invention overcomes this objection; and it consists in certain features of novelty, to be hereinafter described, and then particularized in the claim.

In the drawings, Figure 1 is a longitudinal section of a pump, showing it in practice. Fig. 2 is a cross-section. view of the protecting-plate at. the lower end of the pipe. I I

1 is a half-cylindrical section made of wood and provided with a longitudinal bore 2. Secured to each side of the fiat surface of the semicylindrical section are longitudinal wooden ribs 3 3, curved to conform to the curved surface of thesemi-cylindrical portion and having between them a groove 4, the whole forming a pipe or cylinder constructed with the longitudinal groove 4 and the longitudinal bore 2 at the back of the groove. The lower end of the pipe or cylinder has fitted thereto a friction-plate 5, constructed with an opening Fig. 3 is a detail' tion-plate 5 protects the lower ends of the piping from the destroying friction of the chain and buckets. The piping is constructed preferably of white pine and may be run into any other well than a bored well. The piping is provided with the usual casing and spout, as will be readily understood by those skilled in the art.

What I claim as new is The herein-described piping for a chainpump, the same constructed of a section provided with a bore, ribs applied to said section so as to form a longitudinal groove, and a friction-plate applied to the lower end of the piping and having an opening surrounded by a flange fitting in the lower end of the bore and an upturned lip fitting between said section and the ribs, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
